Headphone Design

Headphone Type

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

In-Ear

Headband Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Acoustic Principle

The basic design of the headphones. There are 3 different types:
Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source.
Closed: Completely sealed and have no air passing through the diaphragms. Sounds like you are in a closed off room.
Semi-open: Have slots or ports in the back of the cup and are partially open. This allows for a mixed sound between an open and closed headphone.

The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".

Working great in noisy environment. Perfectly canceling monophonic sound like street, engine (best result in air jets IMHO), even rain noises, Ideal fit for travelers. One more thing. You can not even use any music players. Just put the earbuds and turn the switch on. You will be pleasantly surprised. It`s not a grave silence but ambient noise is hardly noticed. And be realistic. Don`t expect any magic.

They are comfortable, they do cancel some noise when turned on, but I still found it hard to hear on an airplane. I have a cheap pair of plain earabids that actually work as well, without any noise cancelling.

Great pair for the price. The noise cancelling feature is quite good compared to others in the price range. The sound quality is ok but not excellent. Wouldn't recommend it to daily users but is a must have for frequent flyers/travelers.

We have thrown them in a drawer with all the rest of the junk we have purchased. They do not work as the package claims they will. Even with the noise cancelling feature. We tried them for about 2 months at B***** and N***** because we sit next to a knitting group which gets very loud. We have to turn the volume way up for us not to hear them as they get louder and louder. We are looking at other headsets to see if anyone else has a better set without costing and arm and a leg. Sorry but your headsets do not work as described.

Had a lot of headphones in the past, the bass response for these little headphones is incredible in addition to crisp mids and highs. Better than most brands out there for in ear style head phones. has a on/off sw so must be careful to turn off.

This is the second set of these that I have purchased. I left my first on a plane and I am absolutely sure that whoever found them loves them. What I like best is the they turn off all the noise of airplane sounds and allow me to enjoy the audio books I listen to. Do not hesitate to purchase these. They work really well.

These earbuds sound great for the price when they're on sale. The sound has clear punch and edge. I haven't had a chance to use them outside yet so I can't comment on its noise cancelling feature. I would definitely recommend these

These ear buds to the trick. Small and easy to transport and they block out the low end rumble of airline travel. Easy to operate and use. They made my 4 hour flight much more peaceful. One AAA battery is all the power supply they need but make sure you use your own new battery and not the one that comes with it. Great value for the price.

This product was purchased for its noise cancelling ability so I can not rate it as a musical device. Its intended purpose was to quiet wind noise on long motorcycle trips. Used under a full face helmet on a fully fared sport-touring motorcycle these work better than expected. Wind noise is greatly decrease but tell-tail from the bike, sirens and horns can still be heard.

Good active noise cancelling for the price, nice design, and isolate well the external sound with a good fit too, even without turning it on. By the way that's another good feature - it also works without batteries or turned off, as a regular earbud.

Pretty mighty little guys. They cut off low frequency noise only and you truly notice that immediately after switching to ON. So, you still hear voices of those around you, telephone ringing, etc. They pump rather clear sound, a bit weaker than generic ear buds, but surely wider in the scene. I would say these are worth the try. I will definitely test them in the subway and on board the plane some time later. Recommended for use.

Bought these because I own another pair, but my wife often is using them when I want them. I have other "noise canceling" ear buds that don't work nearly as well. These nearly silence any fan noises, the refrigerator running or any other constant sounds. Work great while mowing also. It is a bit surprising what background noises there are in a room. The fit is comfortable and the battery lasts a long time.
